i still can not believe that back in the old days bbc used to erase tons of the old tv shows episodes to recycle and make room for the new stuff
and i think doctor who the 1963 verison aka classic doctor who was one of the main bbc shows that used to erase some of the older episodes to make room for the new episodes
suggest then you do some reading but I'll give you a hint - cost of storage, it was a time when it was widely believed that the wouldn't be any future demand (the U.K didn't have sydnication) and video tape was very expensive.
And if you research further you'll find that that it was a very common practice.
